Where to start ?

Hello everyone

As a recent graduate in sound engineering, I’d like to get into concert and festival mixing. I’m already a stage technician and work as a sound engineer for small festivals. I recently ran into a colleague who explained to me that sound engineers specialize in the effects of different instruments during live performances. They had a separate console from the main one, a powerful computer... I already have a powerful computer but I don’t know where to start. I also have a small sound card (the Behringer UMC404HD), but that won't be enough. My setup is as follows: Ryzen 7 9800 X3D with an RTX 5080 and 32 GB of RAM. Is that enough? Is the graphics card essential? Keep in mind that plugins and VSTs mainly use RAM and CPU resources.

Do you have any suggestions? What software should I use for live performances? I use Pro Tools, but it’s more for studio or film work.

Also, what hardware interface should I use to minimize latency between the input and output of audio tracks on my computer? Dante seems like a good solution, but the PCIe card is very expensive... any alternatives?

Thank you for your answers
